# Concurrency

> How many jobs your workspace can run at the same time.

Each workspace can have a limited number of unfinished (`queued` or `running`) jobs at the same time. The default limit is **3**.

Check your current usage and limit with `GET /account`:

```json theme={null}
{
  "object": "account",
  "balance": { "amount_usd": "10.000000", "enabled": true },
  "concurrency": { "active": 2, "limit": 3 }
}
```

When the limit is reached, `POST /videos/generation` returns `429` with a `Retry-After` header. No job is created and you are not charged.

```json theme={null}
{
  "error": {
    "type": "rate_limit_error",
    "code": "concurrency_limited",
    "message": "The workspace has reached its concurrent job limit",
    "request_id": "req_..."
  }
}
```

Wait `Retry-After` seconds and retry with the same `Idempotency-Key` and body. For batch workloads, keep a local queue and submit a new job only when an earlier one reaches a final status.
